Segmented Cement Bond Tool

Product Overview

The Segmented Cement Bond Tool (SCBT) provides the operator with an accurate and economic means of inspecting
the quality of the cement bond to casing and formation.

The SCBT evaluates the cement bond quality and integrity to both pipe and formation by providing the measurements
of the cement bond amplitude (CBL) through the near receiver (3-ft crystal), and variable density log (VDL) through
the far receiver (5-ft Crystal). The SCBT tool also provide a cement map through eight segmented receivers, each
segments covers a 45° section of the pipe.

The same bond measurement is available as an analog tool and a high speed digital tool. In the digital tool
all sonic data is captured and stored digitally within 2 ms allowing flexibility of the output telemetry. This tool
is easily configured to customers requirements. The separate acquisition and output module allows changes to the
output telemetry to be easily accomplished.

The analog tool requires ten cycles in order to transmit all of the data to the surface. This requires slower
logging speeds for the same vertical resolution.

These tools are designed for high temperature, and high pressure environments. In the near future, this tool
will also be available with an interface to Spartek Systems “open architecture” tool bus., allowing for both memory
and SRO operations.

Primary Features

Applications

Rated for High-temperature and high-pressure environments.

Combinable with Gamma ray , CCL , and temperature sensors (built in on the digital tools)

The output can be configured to emulate most bond tools available today.

Compatible with most surface systems.

Runs on all standard wirelines.

Combines with all standard pulse tools on the bottom

All receivers are built in a slotted housing to provide rigidity, strength, and noise isolation.
